We face difficulty in individual canine retraction in the bracket system lacking power arms on the canines. When orthodontic force is applied through the center of resistance (CR), then, tooth translation ensues. Forces applied at a distance from the CR create a moment that tends to rotate and tip the tooth. The tendency of tipping is increased in the bracket system lacking power arm, since, force is applied more occlusally. Hence, we have designed a chair side custom made jig to retract the canines individually
